On 9 October 2016, insurgents of the Arakan Rohingya Salvation Army (ARSA) launched their first large-scale attack on Burmese border posts on the Bangladesh–Myanmar border,[15] with a second large-scale attack on 25 August 2017, leading to new "clearance operations" by the Myanmar government, which critics argue targeted civilians.[16]

After ARSA's attacks on 25 August 2017, a troop of around 80 Burmese soldiers arrived in Inn Din on 27 August to recruit local RakhineBuddhist villagers for "local security". Members of the Tatmadaw (armed forces), the Border Guard Police (BGP) and the local Rakhine community began torching Rohingya homes, whilst keeping Rakhine homes intact. The destruction in Inn Din was confirmed by satellite evidence obtained before and after 28 August. Several hundred Rohingya villagers fled from the west hamlet of Inn Din to the mountains in the east, many with the intent to escape to refugee camps in Bangladesh.[1]

On 1 September, many of the villagers who were hiding in the mountains began descending to the beaches of Inn Din in search of food. Armed soldiers and paramilitary members arrived and detained ten men at the beach, whom they accused of being members of ARSA. According to local Rakhine eyewitnesses, the men were moved to the village school at around 5:00 PM, photographed, given a change of clothes, and fed what was to be their last meal. The next morning, on 2 September, the men were photographed again by the military, kneeling on the ground. They were then marched up a hill and shot in the head by soldiers. Soe Chay, a retired soldier and local who supposedly helped dig the mass grave, told Reuters that each victim was shot two to three times. According to Chay, some of the victims managed to survive and made noises whilst being buried alive, prompting a group of local paramilitaries to hack them to death with machetes.[1]

Through a Facebook post by Senior General Min Aung Hlaing, the Tatmadaw (armed forces) announced they would investigate reports of a mass grave in the village of Inn Din.[17] On 10 January 2018, the military released their findings in the investigation through a second Facebook post by Min Aung Hlaing. The post stated that there was indeed a mass grave in Inn Din containing bodies of Rohingyas, but that no massacre took place and that those in the grave were "Bengali terrorists" that soldiers had detained in the village cemetery. According to the post, the Rohingyas in the grave were executed by security forces on 2 September 2017, after they were determined to be "Bengali terrorists".[18] This was the first time the military acknowledged extrajudicial killings perpetrated by soldiers during their "clearance operations" in the region.[7]

A statement on behalf of the military was posted by Min Aung Hlaing to his Facebook page on 10 April 2018, announcing that seven soldiers had been convicted of murder for their participation in the executions. They were sentenced to ten years in prison with hard labour in a "remote area".[3]

On 12 December 2017, members of Myanmar's police force arrested Reuters journalists Wa Lone and Kyaw Soe Oo at a restaurant in Yangon after inviting them to dinner.[19] The pair was charged with possessing classified documents in violation of the colonial-era Official Secrets Act, which carries a possible sentence of 14 years in prison.[20][21]

The two journalists were independently investigating the mass grave found in Inn Din prior to their arrest.[19] A police witness, Moe Yan Naing, later testified that their arrest was a case of entrapment,[22][23] and that their arrest was intended to intimidate journalists.[24][25] After the court held its final preliminary hearing of their case, on 8 February 2018, Reuters released all the findings in their journalists' investigation.[26][27]

On 3 September 2018, the two journalists were found guilty by a court and sentenced to seven years in prison,[28][29][30][31] despite international criticism.[32][33]
An appeal was filed on 5 November 2018 by the journalists' lawyers.[34]

Wa Lone and Kyaw Soe Oo have received international awards for their reporting of the Inn Din massacre, and were included in Time magazine'sPerson of the Year 2018, which recognised persecuted journalists as "guardians" in a "war on truth".[35]

Myanmar: Prior to Reuters' publication, Myanmar government spokesman Zaw Htay responded to the alleged abuses at Inn Din by saying that the government would investigate them if there was "strong and reliable primary evidence".[36] After the publication was released, Zaw Htay announced that the government would take "action according to the law" against the perpetrators of the massacre, but noted that it was not a response to the publication.[37] Burmese authorities later investigated the Rakhine village administrator who spoke with Reuters.[38] The office of the President of Myanmar announced on 13 February 2018 that 16 suspects had been detained in connection to the massacre. Among them were four military officers, three Tatmadaw soldiers, three policemen, and six villagers. Seven of the suspects were later found guilty of murder.[2]

United States: Nikki Haley, the U.S. ambassador to the United Nations, spoke to the U.N. Security Council on 13 February 2018, calling the Myanmar government's denial of the massacre "preposterous" and the restrictions on travel in Rakhine State a deliberate act to "prevent access to an organisation that might bear witness to their [security forces'] atrocities". Haley also called for the release of the two Reuters journalists who were allegedly imprisoned for their coverage of the massacre.[39] After charges were brought against the two Reuters journalists, the American embassy in Yangon expressed its disappointment, urging authorities to "allow the journalists to return to their jobs and families" and calling the decision "a setback for press freedom and the rule of law in Myanmar".[40]
